Image Streamer production configurations

For production deployments, Hewlett Packard Enterprise requires the Image Streamer configuration to be highly available by following these guidelines:

  • The number of frames in the Image Streamer configuration must match the number of frames in the logical enclosure. A logical enclosure is configured of 2 to 5 frames.

  • Two Image Streamers per logical enclosure configuration is required.

  • Only one Image Streamer is allowed per frame. Depending on the configuration, the appliance module can be installed in either appliance bay 1 or 2.

  • For Image Streamer to have redundant paths over which to provide OS images to compute modules, one redundant data fabric per logical enclosure is required. Each fabric includes one master switch configuration, so that multiple interconnect link modules can support the master interconnect module.

Production Image Streamer configurations can be deployed across two, three, four, or five frames with a management ring size as small as the logical enclosure size.

For information about Image Streamer configurations and cabling, see the HPE Synergy Cabling Guide on the Hewlett Packard Enterprise website (http://www.hpe.com/info/synergy-docs).

Two-frame HPE Synergy Image Streamer configuration

Each management ring requires a redundant pair of uplinks to the management network. Accordingly, a two-frame Image Streamer configuration is only possible if the two frames are part of a management ring that is larger than two frames. Doing so allows all four MGMT ports in the two-frame configuration to be used for Image Streamer data connections to the production Ethernet fabric.

Three-frame HPE Synergy Image Streamer configuration

A three-frame Image Streamer configuration has the same Image Streamer cabling requirements as the two-frame configuration with the third frame providing the management uplinks. Although connecting both management uplinks to the same frame is not preferred, it is supported. Connecting both uplinks to the same frame allows the three-frame configuration to support an HA pair of Composer modules. If a three-frame configuration is part of a larger management ring, it is possible for the management uplinks to be connected to different frames within the management ring. This configuration depends on the size of the management ring and the size of any other Image Streamer configurations that are part of the management ring.

Four and five-frame HPE Synergy Image Streamer configuration

A four-frame Image Streamer configuration is an optimal configuration because it supports the ability to populate a single appliance module per frame. This configuration provides for independent HA deployments for both Image Streamer and Composer. Cabling requirements are the same as a three-frame configuration while allowing the opportunity for the management uplinks to be connected to different frames.

A five-frame Image Streamer configuration is similar to the four-frame configuration with the additional frame connected to the management ring. No additional Image Streamer or management uplink connectivity is required.

Multiple Image Streamer / logical enclosure configurations per management ring are possible as long as the HA and cabling requirements are followed.
